  • Function
    Component of a lipid metabolic pathway that catalyzes biosynthesis of highly unsaturated fatty acids (HUFA) from precursor essential polyunsaturated fatty acids (PUFA) linoleic acid (LA) (18:2n-6) and alpha-linolenic acid (ALA) (18:3n-3). Catalyzes the first and rate limiting step in this pathway which is the desaturation of LA (18:2n-6) and ALA (18:3n-3) into gamma-linoleic acid (GLA) (18:3n-6) and stearidonic acid (18:4n-3) respectively and other desaturation steps. Highly unsaturated fatty acids (HUFA) play pivotal roles in many biological functions. It catalizes as well the introduction of a cis double bond in palmitate to produce the mono-unsaturated fatty acid sapienate, the most abundant fatty acid in sebum.
  • Tissue specificity
    Expressed in a wide array of tissues, highest expression is found in liver followed by brain, lung, heart, and retina. A lower level is found in breast tumor when compared with normal tissues; lowest levels were found in patients with poor prognostic index.
  • Pathway
    Lipid metabolism; polyunsaturated fatty acid biosynthesis.
  • Sequence similarities
    Belongs to the fatty acid desaturase family.
    Contains 1 cytochrome b5 heme-binding domain.
  • Developmental stage
    Found in fetal heart.
  • Domain
    The histidine box domains may contain the active site and/or be involved in metal ion binding.
  • Cellular localization
    Endoplasmic reticulum membrane.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 52 kDa
    Observed band size : 45 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 62.5 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 2 minutes
  • FADS2 was immunoprecipitated using 0.5mg HepG2 whole cell extract, 5µg of Rabbit polyclonal to FADS2 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, HepG2 whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab72189.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 45kDa:FADS2.

We have in our catalog one anti-FADS2, the reference ishttp://www.abcam.com/ab72189.Unfortunately the homology between the immunogen peptide and therainbow trout FADS2 is only 27% (see attachment). It is therefore veryunlikely this antibody i...
